Ezekiel 33:30-33

30“As for you, son of man, your people are talking about you near the city walls and in the doorways of their houses. One person speaks to another, each saying to his brother, ‘Come and hear what the message is that comes from the Lord!’

31So my people come to you in crowds, sit in front of you, and hear your words, but they don’t obey them. Their mouths go on passionately, but their hearts pursue dishonest profit.

32Yes, to them you are like a singer of passionate songs who has a beautiful voice and plays skillfully on an instrument. They hear your words, but they don’t obey them.

33Yet when all this comes true  — and it definitely will — then they will know that a prophet has been among them.”
